PARTIAL SYNTHESIS OF AROMATIC CAROTENOIDS, TEDANIN, AGELAXANTHIN A, TETHYATENE, AND RENIERATENE
Aromatic carotenoids, tedanin, agelaxanthin A, and tethyatene were synthesized from O-acetyl-β-citraurin derived from natural zeaxanthin, and tethyatene was further transformed into renieratene as the first example of aromatization of an alicyclic ring in
